About Default Ports: Which Default Ports Need to Be Open and Why?

[williewhcheng]

Based on the Ant Media Server GitHub user guide, the following default ports need to be opened for the server to function properly:

TCP:1935 (RTMP)
TCP:5080 (HTTP)
TCP:5443 (HTTPS)
UDP:5000-65000 (WebRTC)
TCP:5000-65000 (This range should only be opened for internal network communication in cluster mode and must not be accessible to the public.)

However, when I use the Azure Marketplace to create a new AMS VM, I noticed the following ports are opened by default. Could you please clarify:

1. Which ports need to be opened for a single VM deployment and why ?
2. Which ports need to be opened in a cluster or multi-cluster environment and why?
